Hello.... @vaghunger

it is important you understand how the application works...

iGO does not recognize folders like save_pongo or ux_pongo etc...
so the application every time you are select an skin renames the folders to save and ux etc...
internal or SDcard it doesnt matter are the same ... if your iGO app is under SDcard > Android/data/....

you said thats every time is loaded the arimi skin ... this means:

1. the arimi plugins are inside the folder ux.
2. the current save folder is named save.

at this point check:
inside the save folder exist the file save.ch ??
with same number (skin*) as indicated inside the SCconfig ??

if yes, delete the folders save_arimi and ux_arimi and then try again.......
